The simultaneous generation of an electron beam with high energy and high current density with a high-fill factor is challenging for a backward wave oscillator (BWO) and other linear-beam devices. To ...

Scientists have discovered a revolutionary new method for creating quantum states by twisting materials at the M-point, ...

When Br dopant was added in addition to Cu, the codoped ZnS NCs showed much stronger PL emission (∼5 × ) compared to the undoped or Cu-doped sample. In conjunction with time-resolved PL results, this ...
